conference paper description
Many individuals with Autism Spectrum Disorder (ASD) and ADHD often seek out deep touch pressure (DTP). Weighted blankets, vests and other wearable garments have been used to provide DTP, but each suffers from significant limitations. We designed an alternative using shape memory alloy (SMA) springs that contract when heated to create a children's deep pressure vest that can constrict on command, while being simultaneously low profile and adjustable. The garment can be controlled via wireless remote, allowing wearer selfadjustment and enabling the child's parent, guardian, or occupational therapist (OT) to give a comforting "hug" potentially from anywhere in the world.
